So I tried running the vs2017 C++ redistributables (x64) first thinking that then the Rhino installer would check to see if that prerequisite was fulfilled but I don’t think that’s the case. The installer still searches over the network for that C++ redistributable. Even though I have a local copy for it in the same directory and in a redist folder and the machine actually already has that redistributable.

I have this version of the Rhino 6 installer rhino_en-us_6.0.18016.23451.exe
This one I noticed goes out for the 2015 C++ redistributable and completes without any issues.

Part of why I would like to get the latest build to install correctly is because a project team will be starting up soon and I like to keep the builds consistent across all machines ~20. This build rhino_en-us_6.0.18016.23451.exe has some issues. None of the teams have admin privileges.

This is SR4 - rhino_en-us_6.4.18130.19341.exe, I’m having issues with this build
This is initial SR0 release, installs without issues

Installer needs 2017 C++ redistributables for Windows 7 and 10.

The teams don’t have admin privileges so if I install an older version the individuals will not be able to update their own machines because they don’t have admin. So i’m trying to install for all the machines SR4 - rhino_en-us_6.4.18130.19341.exe because its whats on the website.

I noticed that updates from older versions work for instance SR0 to SR4 but not straight installs of SR4 - rhino_en-us_6.4.18130.19341.exe does not.

@nicholasn, thanks for posting your install log after the initial install failed. Can you please run the installer again, now that you’ve installed the 2017 C++ redistributables, and attach a newer log file?

These lines are trying to verify that the file that you’re installing is, in fact, the file that we want you to install. And for some reason the cryptographic signature of that file is failing. It’s also interesting that the failing file is actually the Visual Studio 2015 C++ Redistributables, not the 2017 ones that Pascal recommended. (Here’s a download link for Visual Studio 2015 C++ Redistributables)

There’s definitely something strange going on with installation on your computer. While you’re trying to get it going on your end, I’ll ask some other folks here if they know how to deal with these kinds of messages.

@nicholasn it appears that our installer is trying to verify the Authenticode digital signature for each of the packages it is trying to install. We’re doing this to make sure that somebody doesn’t drop a modified package into the installer and get unauthorized content into your machine.

The trouble seems to be that your computer doesn’t have the root certificates required to verify the packages from Microsoft. It appears that you’ve already downloaded all the content using the dialog in your first post. In order to see which root certificates are missing:

right click each of the exe and msi files in the redist folder

click Properties.

On the digital signatures tab, double click the signatures in the signature list

You should see “This digital signature is OK” - if not, you’ll need to click “View Certificate”, then look at the Certification Path tab to see which intermediate and root certificates are missing.
